Hello there, Hussain. You will need to cancel your QuickBooks Online account in Canada and set up a new one for Saudi Arabia.
Here's how:
Sign in to your QBO account and click Subscription and Billing under the Gear icon.
Then select your company name to take you to your subscription page.
Find the product you wish to cancel, then select Cancel.
Follow the on-screen steps. After your cancellation is successful, you’ll get a confirmation.
Before canceling, please make sure to save your data by exporting it. Or, if you have QBO Advanced, back up your company data to keep a copy of your financial records.
